Facile Synthesis of Poly (N-isopropylacrylamide) Coated SiO2 Core-shell Microspheres via Surface-initiated Atom Transfer Radical Polymerization for H2O2 Biosensor Applications
In this study, inorganic/organic composites containing poly (N-isopropylacrylamide) coated core-shell SiO2 microspheres were prepared via surface-initiated atom transfer radical polymerization (ATRP). The thermal responsive polymer, N-isopropylacrylamide was treated with methanol, water and CuBr/CuBr2/1,1,4,7,7-pentamethyldiethylenetriamine (PMDETA) at room temperature to form PNIPAM@SiO2 microspheres. The as-prepared PNIPAM@SiO2 microspheres were characterized by FT-IR, TGA, XPS, SEM, TEM analyses. Hemoglobin (Hb) was immobilized onto the surfaces of PNIPAM@SiO2 microspheres via hydrophobic and pi-pi stacking interactions. The as-prepared Hb/PNIPAM@SiO2 electrode exhibits well-defined redox peak at a formal potential of ?0.38 V, validating the direct electrochemistry of Hb. The Hb immobilized composite film retained its bioelectroactivity without any significant loss of catalytic activity. The modified electrode detects H2O2 over a wide linear concentration range (0.1 muM to 333 muM) with a detection limit of 0.07 muM. This modified electrode also successfully detects H2O2 from food and disinfectant samples with appreciable recovery values, validating its practicality. We believe that PNIPAM@SiO2 composite has great potential to be used in the detection of H2O2 and development of other enzyme based biosensors.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
